Ipayipi le-ERWamathemba entuthuko kanye nezinkinga ezibhekene nazo

I-Resistance welding imfushane ngepayipi lensimbi le-ERW elinenani lezinzuzo, njengokukhiqiza okuphezulu, izindleko eziphansi, ukunemba okuhle kwe-dimensional, ukubukeka okuhle.Kodwa-ke, esikhathini esidlule, ngenxa yokuthembeka okubi kwe-weld, ukulinganiselwa okukhulu ekusetshenzisweni.Ingxenye yokukhiqizwa kwamapayipi amancane.

I-ERW steel pipe welding mechanism yenza izimpumelelo ezithokozisayo, futhi lo mbono njengomhlahlandlela wokuthuthukisa.Ubuchwepheshe bokulawula okuzenzakalelayo bokuthuthukisa amapharamitha anikeziwe ukuze kuqinisekiswe ikhwalithi yokushisela iba ngcono kakhulu;ngenxa yokuthuthukiswa kobuchwepheshe bokutholwa kwe-ultrasonic, umtshina we-ultrasonic flaw Wong stack trace ukuthola kungatholakala emgqeni wokukhiqiza;ngenxa yokuthuthukiswa kwezinga lokuzenzekelayo.Ukufakwa kwesinyathelo sokwelashwa kokushisela (okujwayelekile) kulayini wokukhiqiza.Ukuthuthukiswa kokusebenza kwe-weld.

Ngaphezulu kwezinhlelo zokusebenza ezimbalwa zobuchwepheshe, kuthuthukise kakhulu ukwethembeka kwamapayipi ensimbi e-ERW.Ukwenza kube ububanzi obuningi bezinhlelo zokusebenza.Njengamanje, okunye ukukhiqizwa komhlaba wonke kwe-ERW steel pipes pipe plant kungasetshenziswa ezindaweni ezibandayo, futhi amazwe amaningi abesakha ulayini wokukhiqiza wamapayipi we-ERW.

Kusukela emazweni ukukhiqizwa kwamapayipi e-ERW, ngaphezu kokukhiqiza okuphezulu kwangaphambilini, okuphansi ekuhlinzeni, ukunemba kobukhulu kusuka ngaphandle, amandla aqinile we-weld.Ukwelula nokushwabana, ukuhlolwa okugobayo kumanani wokuqina womthelela wegumbi lokushisa kungahlangabezana nezidingo ezibekiwe.Kodwa kunenqwaba yabakhiqizi be-ERW steel pipe eshisela ukuqina okuphansi kwezinga lokushisa eliphansi, okukhawulela ukusetshenziswa kwabo ezindaweni ezibandayo.

Inani lokufaka ukushisa, isivinini se-welding, i-convergence angle nezinye izici zihlotshaniswa nokuqina kokushisa okuphansi kwe-weld, inani elikhulu lomsebenzi owusizo lwenziwe kulokhu.Weld nhlangothi zombili ijubane Welding ebusweni kufanele kube eduze komunye nomunye inqubo ukubumba, Welding abandayo, futhi weld ezimbili, ngenxa ncibilika metal uthululelwa ebusweni isivinini ahlukene, ezifana ijubane langaphambili kwenzeka uma ijubane yokugcina kuyinto. enkulu intando more ukuhlasela angaphandle inani FATT anda, izincwadi Kunconywa convergence angle 5 kuya 6. Isivinini Welding kangcono 20m/min izimo ezithile ukuhlaziya ethize, ngikholelwa ukuthi ngemva kokuhlolwa eziningana ukuthola inqubo Welding engcono, ngaleyo ndlela ngcono izinga lokushisa eliphansi ukuqina we weld.
